CaCO3 +2HCl = CaCl2 + H2O + CO2
CaCl2=(электролизация=Ca + Cl2
2Ca + O2 = 2CaOCaO + H2O = Ca(OH)
2Ca(OH)2 + CO2 = CaCO3 + H2O
CaCO3 + CO2 + H2O = Ca(HCO3)2
Ca(HCO3)2 =(t)= CaCO3 + H2O + CO2

2Ca + O2 = 2CaOCaO + H2O = Ca(OH)
2Ca(OH)2 + CO2 = CaCO3 + H2O
CaCO3 + CO2 + H2O = Ca(HCO3)2
Ca(HCO3)2 =(t)= CaCO3 + H2O + CO2
2) 2СО + О2 = 2СО2
3) СО2 + 2КОН = К2СО3 + Н2О
4) К2СО3 + Mg(NO3)2 = MgCO3 + 2KNO3
CH₄ + 2O₂ (t)= CO₂ + 2H₂O
CO₂ + Ba(OH)₂ = BaCO₃↓ + H₂O
BaCO₃ + CO₂ + H₂O = Ba(HCO₃)₂
Ba(HCO₃)₂ + Ba(OH)₂ = 2BaCO₃↓ + 2H₂O
BaCO₃ + 2HNO₃ = Ba(NO₃)₂ + CO₂↑ + H₂O
